How can I force a system shutdown with systemctl hibernate

my inxi dump is below. the system does not shutdown (cpu is alive and fan spinning) when I issue

sudo systemctl hibernate

are there any logs that would show what is going on? I think this may be a conflict between desktop managers.
Thanks everybody.

maybe you need the command pm-hibernate

pm-hibernate does the same thing: I get a black screen and the CPU and fan does not stop. Do you know what to look for in the logs?

How about using systemctl suspend?

This might be of some use for insight and troubleshooting:

It's also important to note that hibernation in Ubuntu is disabled because there are issues with it on some computers, so it might not work for everyone

@stephenbbb you can shutdown a system with sudo poweroff but I guess you don't want to do that. You want your system to hibernate and later wake up.

My suggestion is 1) send a message to syslog that you're going to sleep (logger "Zzzz ... going to sleep now ..."), 2) open syslog (tail -f /var/log/syslog) and look at the messages.

this is the direction I want to go. please, provide more detail. do I send the message and then try to hibernate? or you just want to check if logging works? is there a brief reference to working with the logs?

You could use WOL (wake-on-LAN). You need to enable this in the system's BIOS (in the network settings), then you send a magic packet to wake up the system. It works in a LAN env. To wake up your system from across the Globe is far more complicated. This article may help.

I can get the log from trying pm-hibernate.
are there people who can debug that? it is quite long.
sudo poweroff works and shuts down, but hibernate goes into black screen without ever shutting down.
I am ready to post the log if there are volunteers.

I have some bad news to report here. The code for hibernation is not being developed/debugged any more. there was a pm-utils developer group, but the last posts in the newsgroup are from 2017. I found threads with same complaint like mine that did not get resolved. Looks like the Linux kernel can hibernate on some hardware, but not on many. So, I am unlucky with that laptop.

i use this to get hibernation to work:


if [[ $UID != 0 ]]; then
echo "Only tested on Ubuntu MATE 21.10"
echo "Please run this script with sudo or root privileges to enable hibernate"
echo "sudo $0 $*"
exit 1

#Change this value to size the swapfile X times your ram

#Compute ideal size of swap ( Mem size * 1.5 )

echo "SWAP_FILE_SIZE will be $SWAP_FILE_SIZE bytes"
echo "Creating new swapfile, please wait, this may take a few minutes."
swapoff /swapfile
dd if=/dev/zero of=/swapfile bs="$SWAP_FILE_SIZE" count=1024 conv=notrunc
mkswap /swapfile
swapon /swapfile

# Get UUID & swap_offset

ROOT_UUID=$(findmnt -no SOURCE,UUID -T /swapfile |cut -d\  -f 2)


SWAP_FILE_OFFSET=$(filefrag -v /swapfile | awk '{print $4}' | head -4 | tail -1 | cut -d'.' -f1)


echo "Modify initramfs"

echo "RESUME=UUID=$ROOT_UUID resume_offset=$SWAP_FILE_OFFSET" | tee /etc/initramfs-tools/conf.d/resume
